Exciting stuff...Looking forward to learn more about this engine and see how she performs.

Have you got any videos of it performing in its final incarnation under real life loads?or even better, using something like a welder while starting a compressor or pump and/or using a vacuum cleaner? We use this method for testing the grit of offgrid power systems we install.

we will be posting videos to our website in a matter of weeks, but we are planning to show the performance of this unit becoming the primary heat and power source for the entire house and using the grid connection as a back up if needed or the option of being able to sell excess power back.

Will the units have a burner that accepts all types of fuel, or will different add ons have to be installed? For example, can I hook a propane line into it and switch to pellets when I have them? Im also thinking about the insurance company. They will probably see it like a boiler and their rules are that wood/pellets are only allowed (as backup) if there is a primary gas heating system in the house.
